Database persistence? No way, not with that production database schema restriction. File persistence? Sounds like a recipe for disaster. In-memory replication is the clear winner here, assuming you have the RAM to spare.

Ah, the age-old session persistence dilemma. In-memory replication is the way to go, as long as you have a robust caching solution. Otherwise, you might end up with a memory-hogging 'in-memory' nightmare!

Hmm, I don't know, in-memory replication seems risky with little free memory. Maybe file persistence is a safer bet, even if it's not as performant.

I was thinking D) Whole-server migration, but that might be overkill for just session persistence. In-memory replication sounds more appropriate.

That's a good point, but I still think C) In-memory replication is more efficient given the constraints we have.

C) In-memory replication seems like the best option here. It meets the high availability requirement while avoiding the database and file system constraints.

I disagree, I believe A) Database persistence is the best option because it ensures high availability even when multiple machines fall simultaneously.

I think the best option is C) In-memory replication because it doesn't require updating the production database schema.
